Dynamic MRI of cervical spine on sitting position, as a prediction of cervical spondylosis

随着我国社会老龄化的加剧，颈椎病患者不断增多。但有时患者的病情与MRI图像不一致，因此在临床实践中成为问题。比较颈椎病患者与非颈椎病患者坐位的动态MRI图像，探讨是否存在常规背位和静态MRI图像不能诊断的因素。颈椎病患者的硬脊膜囊有除脊柱外体积较小的趋势。然而，在动态状态下的变化量并没有接受显著的差异。

The patients of cervical spondylosis has increased while society is aging in our country. But sometimes patient's condition and the MRI image do not agree, so it becomes problem in clinical practice. It was examined whether there would be any factor which cannot diagnose by usual dorsal position and static MRI images in comparison of dynamic MRI images on sitting position of cervical spondylosis patients and non-cervical spondylosis patients. There was a tendency that cervical spondylosis patients showed less volume besides the spine in dural sac. However, the amount of change in a dynamic state did not accept a significant difference.
